Asthma Nursing Care Management and Study Guide

Asthma is a chronic inflammatory disease of the airways characterized by hyperresponsiveness, mucosal edema, and mucus production. The underlying mechanism involves reversible airway inflammation where mast cells release inflammatory mediators, leading to bronchoconstriction, increased blood flow, and airflow limitation.

Common symptoms include cough, dyspnea, and wheezing, frequently occurring at night or early morning. Severe cases may progress to status asthmaticus or respiratory failure. Prevention focuses on identifying and avoiding allergens and irritants, effectively managing symptoms, and disease education.

Treatment involves a combination of short-acting beta2-adrenergic agonists for acute relief, along with corticosteroids, anticholinergics, leukotriene modifiers, and immunomodulators for long-term control. Peak flow monitoring is essential to measure airflow and guide management decisions.

Nursing management includes assessing respiratory status, breath sounds, and oxygen saturation. Key nursing diagnoses involve ineffective airway clearance, impaired gas exchange, and anxiety. Interventions prioritize maintaining airway patency, administering prescribed medications, fluid therapy (if dehydrated), and providing patient education for home care adherence.
